Thanks. Yes, those are the instructions I was following. I did quote the indi github link in the OP. It's the pyindi-client where I was having trouble, and the official repo for that is still under svn via Sourceforce as far as I can see.

In the two weeks it has taken to move this post out of moderation, I've had help directly from geehalel and worked out that nothing was actually wrong, I'd just got some dependencies all mixed up with different versions of packages. The current build of indi requires libnova-0.14 but Raspbian ships with libnova-0.16 and indi does not work unless you downgrade libnova. At some point I had both versions of libnova installed, and so once I cleared everything out and rebuilt both indi and pyindi-client against the same dependencies, it all worked fine.

I can confirm it all works just fine now on a Pi 3 with the current latest Raspbian.

Thanks for your help!

Hello,

I'm attempting to install libindi and pyindi-client on a Raspberry Pi 3 running the latest build of Raspbian.

$ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

$ uname -r
4.4.50-v7+

I have built from source the latest version of libindi ( github.com/indilib/indi ) and pyindi-client ( svn.code.sf.net/p/pyindi-client/code/ ) and there were no errors, everything built ok. I believe I have all the necessary dependencies installed. indiserver starts up fine so I believe the server installation is ok.

However, when I try to import PyIndi into Python 3 I get the following error:
$ python3
